Recent transport network development using ROADMs and 40G transmission

摘要：

This paper overviews the recent transport network development using reconfigurable optical add drop multiplexers (ROADMs) and 40G transmission technologies. High-speed transmission technologies with the line-rate of 40G or 100G are reviewed first. Then, the advanced modulation format suitable for constructing the metro-core 40G ROADM network from the viewpoints of impairments is discussed. Finally the advanced functionalities that enhance ROADM network agility are described.
